  • Patent number: 8028480
    Abstract: This application describes a wall construction and method of making the same in generally a Piece-en-piece mode. A vertical mortise is provided in adjacent vertical timber members and vertical mortises are cut into the end faces of horizontal timber members expected to be placed between adjacent vertical member. When the horizontal timber members are in place the vertical mortises align and wooden or metal splines can be inserted into the mortises thus securing the horizontal members laterally while still allowing them to move vertically to account for, for example, shrinkage in the wood. By substituting a mortise for a tenon, this invention reduces manufacturing costs and reduces assembly time and costs, as each horizontal timber can be set directly into place without lifting it to the top of the upright timber members.

    Abstract: Interlocking tongue and groove floor and wall panels use multiple bonded sheet construction, preferably three sheets, of material, such as plywood, bonded together Other rigid durable sheet materials may be used. The shape is preferably either square or rectangular. By offsetting the middle sheet layer so that two adjacent sides extend beyond the top and bottom layers which are in registration, a tongue is developed on two adjacent sides while the opposite sides will have grooves. Thus such panels can be used to cover a large floor or wall area using normal tongue-in-groove techniques by fitting the protruding tongues into the grooves of adjacent panels In an alternate embodiment, the middle sheet is smaller in size than the top and bottom sheets which are in registration. The middle sheet is centered within the top and bottom sheets thus forming grooves on all four edges.

  • Patent number: 7805903
    Abstract: A locking system for floor boards comprises a plurality of floor boards and a plurality of locking devices. Each floor board has two tongues on one lateral side and another tongue and a locking groove on the opposite lateral side. The floor board also has two grooves on its bottom side. The locking device has three protruding gripping extensions. Few locking devices are placed on each floor board before the floor boards are sent to a job site. At the job site, two adjacent floor boards are assembled together by inserting the tongue of one board into a space defined by the locking device and the tongues of the adjacent board. The tongues are further secured in place by compression of flexible buffers located at each protruding gripping extension.
